2. PARTS REPLACEMENT
The section explains the procedures for replacement of parts, assemblies, and units in the field. Onlythe disassembly procedures are explained here. For reassembly, reverse the disassembly procedure.
2.1 Precautions for Parts Replacement
(1) Before starting to replace parts, remove the AC cord and interface cable.
(a) Remove the AC cord in the following sequence:
i) Turn off (“o”) the power switch of the printerii) Disconnect the AC inlet plug of the AC cord from the AC receptacle.iii) Disconnect the AC cord and interface cable from the printer.
(b) Reconnect the printer in the following procedure.
i) Connect the AC cord and interface cable to the printer.ii) Connect the AC inlet plug to the AC receptacle.iii) Turn on (“l”) the power switch of the printer.
(2) Do not disassemble the printer as long as it is operating normally.
(3) Do not remove parts which do not have to be touched; try to keep the disassembly to a minimum.
(4) Use specified service tools.
(5) When disassembling, follow the laid out sequences. Parts may be damaged if these sequences arenot followed.
(6) Since screws, collars and other small parts are likely to be lost, they should temporarily be attachedto the original positions during disassembly.
(7) When handling IC’s such as microprocessors, ROMs and RAMs, or circuit boards, do not weargloves that are likely to generate static electricity.
(8) Do not place printed circuit boards directly on the equipment or floor.

Functions
Changes the default PDL for each brand. PDLs that are disabled in thismenu will not be displayed at EMULATE of User Menu or OP MENU ofAdmin Menu. (No specific to PCL XL is provided; thus, when DISABLEis set, there is not visual change.)When print data in the PDL language set to DISABLE is received, theprinter will desplay INVALID DATA and discard received data.PS3 EMU will be displayed only when PSE is installed.For PN272/83, PCL cannot be set to DISABLE. (ENABLE must be set tomake it always usable. Even if set to DISABLE, received data will beprocessed.)
Displayed only if an RS232C is installed.Loop Test runs Serial I/F function test without connecting the host PC.The printer alone sends/receives “00”FFH” data.Loop Test requires attachment of a Loop connector (pin2: TD and pin3:RD are shorted) prior to execution.A Loop count is displayed real-time on LCD, and if an error occurs, anerror message will be displayed.This mode can be ended only by turning the power off. Following thisoperation, the power is shut down; thus, the printer cannot go back inOperation Mode or other Maintenance Mode.
PRINTING Rolling ASCII Continuous Print Continuously prints RollingASCII patterns for various types continuos testing on the maker side.(Noise test, engine test).This mode can be ended by pressing the “ONLINE” SW.Following thisoperation, the power turns off, thus, the printer cannot return to eitheroperation mode or any of other maintenance modes.
Set the dot shift for the horizontal direction when printing from Tray 1.This area will not be initialized by the EEPROM reset operation.
Set the dot shift for the horizontal direction when printing from Tray 2.This item is displayed even when Tray 2 is not set. This area will not beinitialized by the EEPROM reset operation. (At first, it is initialized bydefault.)

(*1) The model (forcing) which operated before is for operating as another model (forcing), and a Brands check is recognized as an error and resets change of the Brands point by the PJL command, operation at the time of the power supply injection by new EEPROM, etc. (*2) It restricts to the time when whose page counter is 500 or less sheets, and is reset by 0. (ENGINE RESET by the PJL command is not this limitation.)(*3) Although a DOT SHIFT setting menu exists in a system maintenance menu, since setting value preservation area is arranged at PU EEPROM AREA, even when the system maintenance menu item is initialized, a DOT SHIFT setup is not initialized. On the contrary, when PU EEPROM AREA is initialized, a DOT SHIFT setup is also initialized.

APPENDIX G HIGH CAPACITY SECOND PAPER FEEDER
1. OUTLINE
1.1 Functions
The printer is mounted on top of this High Capacity Second Paper Feeder. The High Capacity SecondPaper Feeder supplies paper automatically through the operation of pulse motor (hopping), which isdriven by signals sent from the printer.The main functions are the followings:
• Paper that can be used:
[Paper Type]• Standard paper: Xerox 4200 (20-lb)• Special paper: OHP sheets (for PPC), Label sheets (PPC sheets); use of envelopes or
thick paper is not possible.• Cut sheet size: A4, A5, B5, Letter, Executive, Legal13, Legal14• Special size: Paper width: 148 to 216mm
Paper length: 210 to 355.6mm
[Weight]• 16-lb to 24-lb (60 to 90 g/m2)
• Paper setting quantity: 500 sheets of paper weighing 64 g/m2

2. MECHANISM DESCRIPTION
2.1 General Mechanism
The High Capacity Second Paper Feeder feeds the paper into the printer by receiving the signal fromthe printer, which drives the pulse motor inside the High Capacity Second Paper Feeder, and this motionis transmitted to rotate the one-way clutch of the hopping frame assembly. The paper is delivered fromthe hopper into the printer through the turning of the hopping roller and feed roller.
Once delivered into the printer, the paper is then controlled and fed through by pulse motor (registration)of the printer.
2.2 Hopper Mechanism
The hopper automatically feeds the printer with the paper being set, single sheet at a time. When thepaper is loaded in the paper cassette, it is then transported by the pulse motor, carrying forward only asingle sheet caught by the brake shoe at a time.

3. PARTS REPLACEMENT
This section covers the procedures for the disassembly, reassembly and installations in the field.This section describes the disassembly procedures, and for reassembly procedures, basically proceedwith the disassembly procedures in the reverse order.
3.1 Precautions Concerning Parts Replacement
(1) Parts replacements must be carried out, by first turning the printer power switch off “O” andremoving the printer from the High Capacity Second Paper Feeder.
(2) Do not disassemble the High Capacity Paper Feeder if it is operating normally.
(3) Establish the extent of disassembly suitable for the purpose of the procedure, and do notdisassemble any more than necessary.
(4) Only specified service tools may be used.
(5) Disassembly must be carried out according to the prescribed procedures. Parts may be damagedif such procedures are not followed.
(6) Small parts such as screws and collars can easily be lost, therefore these parts should betemporarily fixed in the original location.
(7) When handling printed circuit boards, do not use any glove which may generate static electricity.
(8) Do not place the printed circuit boards directly on the equipment or floor.
[Service Tools]
Table 3-1 shows the tools required for the replacement of printed circuit boards, assemblies and unitsin the field.
